Description

Technical Field

[0001] This utility model relates to the technical field of polyurethane processing equipment, and in particular to a gas recovery throttle valve for polyurethane potting resin processing station. Background Technology

[0002] Polyurethane potting resin (PU potting compound) is a material characterized by urethane bonds and polymerized from polyols and isocyanates. Its core advantages lie in its elasticity, insulation, weather resistance, and designability. Its hardness and temperature range are adjustable, and it also has the processing characteristics of low shrinkage, high adhesion, and rapid room temperature curing. It can meet the needs of the electronics industry (circuit, LED packaging), automotive new energy (battery pack, sensor protection), industrial and aerospace (motor insulation, aerospace equipment packaging) and other fields.

[0003] During the synthesis and processing of polyurethane potting resin, to prevent the diffusion of toxic and harmful gases, a negative pressure extraction device must be installed at the processing station and connected to a gas recovery and treatment system. The gas must be treated to meet emission standards before it can be released. However, while existing processing stations are enclosed, the need to retain an operating window means that although the negative pressure extraction power is sufficient, the large intake volume, with the majority being harmless gas entering through the operating window, leads to an excessive amount of gas being extracted into the gas recovery and treatment system. When this exceeds the processing load, it severely impacts the extraction power. Furthermore, upgrading the gas recovery and treatment system to increase its processing capacity is too costly. While existing technology allows for the installation of an isolation door at the operating window, the opening and closing of this door is easily affected by the negative pressure, increasing operational difficulty. Therefore, a gas recovery throttling valve that can reduce the intake volume and facilitate operation is needed. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a gas recovery throttling gate for polyurethane potting resin processing station, thereby solving the above-mentioned problem.

[0005] To achieve the above objectives, a gas recovery throttling gate for a polyurethane potting resin processing station is provided, comprising a station body and an outer enclosure. The station body is located inside and below the outer enclosure. A negative pressure pipe is fixedly connected to the top of the outer enclosure. An operating window is provided on the side of the outer enclosure away from the negative pressure pipe. Two inner slide rails and two outer slide rails are respectively provided on both sides of the operating window. A lifting enclosure is slidably connected to the inner side of the operating window via the two inner slide rails, and a lifting glass window is slidably connected to the outer side of the operating window via the two outer slide rails. Both the top sides of the liftable glass window and the liftable fence are fixedly connected to lifting rings. The top of the outer fence is respectively provided with a first pulley group and a second pulley group. Both top sides of the liftable glass window are fixedly connected to glass window steel wire ropes through lifting rings. Both top sides of the liftable fence are fixedly connected to fence steel wire ropes through lifting rings. The ends of the two glass window steel wire ropes away from the liftable glass window pass through the first pulley group and are fixedly connected to a first counterweight. The ends of the two fence steel wire ropes away from the liftable fence pass through the second pulley group and are fixedly connected to a second counterweight.

[0006] According to the gas recovery throttle gate for the polyurethane potting resin processing station, the first counterweight and the second counterweight are both located on the same side of the outer enclosure, with the first counterweight located at the end furthest from the operating window and the second counterweight located at the end closest to the operating window.

[0007] According to the gas recovery throttle gate for the polyurethane potting resin processing station, the first pulley group includes two lifting pulleys corresponding to the position of the outer slide rail and two suspension pulleys corresponding to the position of the first counterweight.

[0008] According to the gas recovery throttle gate for the polyurethane potting resin processing station, the second pulley group includes two lifting pulleys corresponding to the positions of the inner slide rail and two suspension pulleys corresponding to the positions of the second counterweight.

[0009] According to the gas recovery throttling gate for the polyurethane potting resin processing station, magnetic limiters are provided at the top ends of both inner and outer slide rails, and iron plates are fixedly connected at the positions corresponding to the magnetic limiters at both ends of the upper part of the lifting glass window and the lifting enclosure.

[0010] According to the gas recovery throttling gate for the polyurethane potting resin processing station, optical sensors are installed at the positions corresponding to the lifting glass window and the lifting enclosure, both below the top of the outer enclosure.

It also allows for easy opening and closing of the operation window, enhancing the practicality of the device.

[0012] 2. This utility model is equipped with an optical sensor that can detect the height of the lifting glass window and the lifting enclosure, which facilitates the negative pressure suction system to adjust the suction force according to the degree of opening of the operating window, reduces the pressure on the gas recovery and treatment system, and enhances the practicality of the device.

[0013] 3. This utility model is equipped with a magnetic limiter, which can limit the lifting glass window and lifting fence to a certain extent when they reach the top by magnetic force, preventing the lifting glass window and lifting fence from falling when the worker is operating, thus improving the stability of the device.

[0017] This section will describe in detail the specific embodiments of the present utility model. Preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model. The drawings are all in a very simplified form and use non-precise proportions. They are only used to help to explain the embodiments of the present utility model in a convenient and clear way, and should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4 This utility model provides a gas recovery throttling gate for a polyurethane potting resin processing station, including a station body 1 and an outer enclosure 2. The station body 1 is located inside and below the outer enclosure 2. A negative pressure pipe 4 is fixedly connected to the top of the outer enclosure 2. An operation window 3 is provided on the side of the outer enclosure 2 away from the negative pressure pipe 4. Two inner slide rails 5 and two outer slide rails 6 are respectively provided on both sides of the operation window 3. A lifting enclosure 8 is slidably connected to the inner side of the operation window 3 through the two inner slide rails 5. A lifting glass window 7 is slidably connected to the outer side of the operation window 3 through the two outer slide rails 6. Optical sensors 15 are provided at the bottom top of the outer enclosure 2 at positions corresponding to the lifting glass window 7 and the lifting enclosure 8, which can detect the lifting glass window 7. The height of the lifting barrier 8 facilitates the negative pressure suction system to adjust the suction force according to the opening degree of the operating window, reducing the pressure on the gas recovery and treatment system. Lifting rings 9 are fixedly connected to the top sides of the lifting glass window 7 and the lifting barrier 8. The top of the outer barrier 2 is respectively equipped with the first pulley group 10 and the second pulley group 11. Magnetic limiters 14 are set at the top ends of the two inner slide rails 5 and the outer slide rail 6. Iron plates are fixedly connected at the upper ends of the lifting glass window 7 and the lifting barrier 8 at positions corresponding to the magnetic limiters 14. When the lifting glass window 7 and the lifting barrier 8 reach the top, they can be limited by magnetic force to prevent the lifting glass window 7 and the lifting barrier 8 from falling during worker operation, thus improving the stability of the device. Both sides of the top of the lifting glass window 7 are fixedly connected with glass window steel wire ropes 16 via lifting rings 9. Both sides of the top of the lifting enclosure 8 are fixedly connected with enclosure steel wire ropes 17 via lifting rings 9. The ends of the two glass window steel wire ropes 16 away from the lifting glass window 7 pass through the first pulley group 10 and are fixedly connected to the first counterweight 12. The ends of the two enclosure steel wire ropes 17 away from the lifting enclosure 8 pass through the second pulley group 11 and are fixedly connected to the second counterweight 13. The first counterweight 12 and the second counterweight 13 are both located on the same side of the outer enclosure 2, with the first counterweight 12 located at the end away from the operating window 3 and the second counterweight 13 located at the end closer to the operating window 3. The first pulley group 10... Group 10 includes two lifting pulleys corresponding to the positions of the outer slide rail 6 and two suspension pulleys corresponding to the positions of the first counterweight 12. The second pulley group 11 includes two lifting pulleys corresponding to the positions of the inner slide rail 5 and two suspension pulleys corresponding to the positions of the second counterweight 13. The first counterweight 12 and the second counterweight 13 can balance the gravity of the lifting glass window 7 and the lifting barrier 8, allowing the lifting glass window 7 and the lifting barrier 8 to slide up and down more easily to adjust the opening degree of the operating window 3, playing a throttling role on the operating window 3. Moreover, since the direction of movement is perpendicular to the direction of negative pressure, the influence of negative pressure can be greatly reduced, and the operating window 3 can be opened and closed easily.

[0019] Working Principle: During operation, this invention utilizes a liftable glass window 7 and a liftable barrier 8 at the operating window 3. These, along with corresponding counterweights and a steel wire rope connected by a pulley system, allow the liftable glass window 7 and liftable barrier 8 to slide up and down, adjusting the opening degree of the operating window 3. This throttling effect on the operating window 3, and because the direction of movement is perpendicular to the negative pressure direction, the influence of negative pressure is significantly reduced, allowing for easy opening and closing of the operating window 3. Simultaneously, the optical sensor 15 above the liftable glass window 7 and liftable barrier 8 detects their height, facilitating suction adjustment by the negative pressure suction system based on the opening degree of the operating window, thus reducing the pressure on the gas recovery and treatment system.

[0020] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
